I never remember much past V=IR and the white smoke theory of electrical engineering.

I don't judge people by their race, religion, color, size, age, gender, or ethnicity. I judge them by their grammar, spelling, syntax, punctuation, clarity of expression, and logical consistency.

hell, in all honesty, the only thing one should say about how wrong eve is in this bit is, that the capacitors shoudl've been shown in farads and not joules, now that I think about it.


A Farad is a unit of capacitance. A joule is a unit of energy. A capacitor stores energy, not capacitance. Thus the ship's capacitor shows the correct units: joules of stored energy. The farad-rating of the capacitors in the ship doesn't matter. What would make a difference of course is the watt-rating of those capacitors, since energy storage devices in the real world have the same kind of limitation: due to internal resistance, load impedance, and physical construction of the storage unit, some devices are only suited for moderate wattage over a long period of time (e.g.: alkaline batteries) while others are better suited for large wattage over a short period of time (e.g.: lead-acid car batteries).

Thus the Amarr racial bonus to capacitor usage of laser weapons: their capacitors are designed specifically to handle that kind of load. So it's not so much a case that laser weapons get a bonus to capacitor usage, so much as every other use is less efficient.

in addition I ask you this: how many joules does a capacitor witth, let's say, 2200 nano-Farads pack?
Other people have explained that Farad is a unit of capacitance, not capacity, but the answer to your question is: 2.2 µJ per V². Combine that with a safe voltage limit (say, 100V), and you get a storage capacity of 22 mJ.

An example of a top-line commercial ultracapacitor today (2013 CE / YC-21223) has a capacitance of ~90F with a voltage limit of 75V, and can therefore store ~500kJ. It masses 25 kg, for a final density of ~20kJ/kg.



need to go deeper in the electrical part of my course then.


still, this proves that, at the very least, a gigajoule capacitor is quite realistic for EVE.

FFS people..Eve is a game, not an episode of Nova.


That being said, Im still waiting on which of my frigates can go back in time.

Since the cessation of their usefulness is imminent, may I appropriate your belongings?

Technically, since they werent already back in time to tell yourself that you were going to go back in time and give yourself the instructions on how to go back in time to give yourself the instructions, you never will, and theoretically, is impossible for YOU to go back in time. You know, universal consistency paradoxes and whatnot.
